Nine9 3xD and 4xD indexable drill bit
♦ Features
• Smallest dimension
3xD: Ø10 to Ø30 mm.; 4xD: Ø16 to Ø30 mm.
• Smaller cutting chip
> The center and peripheral inserts are positioned in order to divide the cutting chips into smaller spiral shape. It helps the cutting chip to be removed faster and easier.
> Designed for high productivity, high speed cutting. Coolant supply is needed.
• Better surface finish and better diameter accuracy.
> Special insert positioning to balance the cutting forces, better surface finish and diameter accuracy are achievable.
♦ Application of Drill in Different Conditions
♦ Inserts:
• Patented dual-relief angle insert
Primary relief angle is to increase the toughness of the insert, secondary relief angle is to strengthen the axial feed rate.
> Fully ground dual-felief insert, for improved surface finish and higher feed rate.
> Patented Dual-relief angle insert.
> Square insert, 4 cutting edges, reducing cost.
> Honed on the cutting edge, good chip breaking condition.
> Fully ground carbide insert.
• NC2032:
> K20F grade, AlTiN coated, for carbon steel, alloy steel, casting iron, stainless steel and hardened steel up to HRC 50.
• NC40:
> P35 grade, tougher insert with special chip breaker, TiN coated, for low carbon steel and stainless steel.
> Only available for insert N9GX06020431 and N9GX09030831.
♦ 3xD and 4xD tool holder:
• Coolant is supplied by 2-straight coolant holes to ensure enough coolant volume to flush out the cutting chips.
• The insert pockets are arranged to split the cutting chip which makes the cutting chip excavation more efficient.
• The flutes of the drill are non symmetrical there by increasing the rigidity of the tool holder.
